The European Union says technical talks between Iran and the six major world powers will continue following an expert level meeting between the two sides in the Turkish city of Istanbul.
“The technical meeting in Istanbul will be followed by a meeting between Helga Schmid and Dr. Ali Bagheri [the deputy secretary of Iran's Supreme National Security Council]," a statement from the office of EU foreign policy chief Catherine Ashton said on Wednesday.
However, no date was given for their meeting.
Iran and the P5+1 -- Britain, China, France, Russia and the United States plus Germany - agreed to hold the expert-level talks during their negotiations in the Russian capital, Moscow, in June.
The Moscow meetings came after three sessions of plenary talks in Baghdad in May and an earlier round of negotiations in the Turkish city of Istanbul in mid-April.
The two sides had, prior to the Istanbul talks, held two rounds of negotiations, one in Geneva, Switzerland, in December 2010, and another again in Istanbul in January 2011.
"Technical discussions took place in Istanbul on the 3rd of July. These were led by nuclear expert Stephan Klement on behalf of Catherine Ashton, EU High Representative, with experts from the P5+1 meeting with the Iranian team," the statement added.
“The experts explored positions on a number of technical subjects. The meeting lasted for a full day ending at 1 am," it added.
“The experts provided further detail of a proposal given to Iran in Baghdad while Iran shared further detail of their proposal,” the statement said.
